IN GEN DIARY MASS.

Specification of Letters Patent.

Patented Dec. 23, 1919.

Application filed July 15, 1918. Serial No. 245,003.

To all :whom it may concern:

Be 1t known that I, AUGUSTE CHANARD, of 16 Avenue de Paris a Rueil, Seine and Oise, France, chemist, have invented In cendiary Masses, of which the following is a'full, clear, andexact description.

Attempts have already been made to utilize pitches, tars and resins, for the purpose of forming incendiary masses. These bodies, however, are not easily inflammable.

Consequently the creation of fires with these -materlals is laborious and uncertain. Furthermore the fires are not very intense.

The incendiary'mass forming the subjectmatter of the present invention consists essentially: 4

A. Of a substance which, although not easily inflammable at normal temperatures,

is combustible and, preferably, adapted to burn with a long and steadyflame when.

I ignited by contact with a medium at a high temperature. As examples of substances of this kind I may mention tars, pitches, conif- 'tives of natural or artificial greases or tars,

erous or other resins, either natural or artificial, deprived of their natural oil content or not stearic acid, naphthols, naphtholin, Vaseline, or other combustible derivaany of these substances being employed alone or mixed with others. B. To the selectedmass is then added petrol, oil, alcohol, ether or any highly inflammable solvents, appropriate fuels, liquid or solid, singly or mixed together, in such a Way as to obtain either hot or cold at more or less thick paste.

C. In this paste are then embedded, either hot or cold, any substances natural or artificial, mineral or or anic, liquid or solid which are particularl good supporters of combustion, such as: nitrates, chlorates,

peroxid, 'nitrated cellolose, nitratedglycerin, etc., alone, mixed together or combined.

It will therefore be understood that the massobtained will be to the desired extent inflammable and intensely combustible.

The following is one method of puttlng the invention into practice 100 parts of resin and 33 parts of turpentine oil for instance are taken and th Wholeplaced under a gentle fire.

- When all is dissolved 50 parts of celluloid or nitrated cellulose, divided into small above are only given b pieces, are introduced into this mass and distributed as regularly as possible by stirrlng.

The incendiary mass is then ready: the least flame will set it alight with ease and certainty, and the fire will spready briskly and will be violently intense, giving abun- Hdant long and massive flames, thanks to'the double distillation of the components resins and celluloid.

The examples and proportions indicated way of indication and not limitation. Ot er proportions and other methods of preparation may be devised without going outside the principle of the invention.

The incendiary mass'obtained-is poured into any receptacles. of any shapes and dimensions and of any materials; wood, textiles, metals, etc.

The inflammability of this incendiary mass, which is already considerable, may be still further increased by using the ignition device illustrated in the accompanying drawings, in which:

Figure 1 is a sectional elevation of the device embedded in the incendiary mass, and

Fig. 2 is an elevation, partly in section of the device in a different position.

. Referring to Fig. 1, a designates the-incendiary mass in which there is embedded a hollow cylinder 7)" of combustible material, for example celluloid. The cylinder 12 which may measure from 15 to 50 millimeters in diameter according to the size of the mass, is closed at both ends, and filled with a highly inflammable material such as chlps of celluloid or cotton soaked in petrol; A suitable igniting means such as a Bickford fuse cl extends into the interior of the cylinder I).

This ignition relay allows of the sudden ignition of the whole of the incendiary mass,

'to be used for all purposes, industrial or military, whether it be set in operation directly or carried or sent by any means or suitable projectiles. A

It is likewise intended for the charging of the shells called tracers or incendiary shells.

Claims:

1. An incendiary mass comprising resin, a solvent for the latter and nitrated cellulose divided into small pieces and distributed in the mass.

2. An incendiary mass comprising resin, a solvent for the latter and celluloid di vided into small pieces and distributed in the mass.

3. An incendiary mass comprising a combustible substance, a celluloid tube, closed at both ends and introduced in the mass, avery easily inflammable material contained in this "tube, and means for igniting the said material.

4:. An incendiary mass comprising a combusti'ble substance, a body for supporting the combustion, mixed with the said substance,

a celluloid tube, closed at both ends and introduced inthe mass, a very easily inflammable material contained in this tube and means for igniting the said material.

5. An incendiary mass comprising a combustible substance, a body for supporting 85 tion device opening in the middle of the chips of celluloid.

6. An incendiary mass comprisin resin, a solvent for the latter, and celluloi divided into small pieces in the mass; a celluloid tube, closed at both ends and introduced in the mass, chips of celluloid contained in the said tube, and an ignition device open ing in the middle of the chips of celluloid.

7. An incendiary mass comprising a combustible substance, an ignition relay com; prisin a tube of preminently combustible materlal, closed at both ends and introduced in the mass, a very easily inflammable material contained in the said tube, means for igniting the said material, vent holes passing through the incendiary mass and putting this ignition relay into communication With the atmosphere.

8. An incendiary mass comprising a combustible substance, a solvent for the latter, a body for supporting the combustion, an ignition relay comprising a tube of p-reminently inflammable material, closed at both ends and introduced in the mass, a very easily inflammable material contained in the said tube, means for ignitingl the said material, vent holes passing through the incendiary mass and putting the said ignition relay into direct communication with the atmosphere.

The foregoing specification of my incendiary mass, signed by me this twenty-sixth day of June, 1918.

AUGUSTE CHANARD.
